The invention discloses a
renewable energy generation and
fresh water production integrated
system for an isolated island. The
renewable energy generation and
fresh water production integrated
system comprises
solar cell panels, a
wind driven generator, a
seawater electrolytic tank, an
oxygen storage tank, a
hydrogen storage tank, an alkali filtering tank, a
hydrogen combustion chamber, a
seawater heating furnace, a
turbine, a main shaft, a generator, a user, a
heat exchanger, a pipeline, a small heat exchange
pipe, pumps, a coastline, a condenser
pipe and a
water storage tank;
electricity generation is carried out by utilizing randomly fluctuated
solar energy and wind energy;
hydrogen is generated by electrolyzing
seawater, so that
energy storage is realized;
combustion is carried out by utilizing hydrogen; seawater is heated to generate
superheated steam, so that the
turbine is driven to rotate; then, the generator is driven to output the steady power;
tail gas after
hydrogen combustion and water vapour discharged by the
turbine are introduced into seawater for condensation through the condenser
pipe, so that
fresh water is generated;
seawater desalination is realized; energy is effectively utilized in a diversified manner; the problem that power and fresh water are stably supplied when the isolated island is offline can be solved; the
heat exchanger heats seawater by utilizing waste water vapour; therefore, utilization of
waste heat is realized; and the energy utilization efficiency is increased.
